To all whom it may concern:

Be it known that I, THOMAS J. Knrron, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Automobile-Radiator; and I do herebydeclare the following to be a full, clear, and exact description of'theinvention, such as will enable others skilled in the art to which itappertainsto make and use the same, :reference being had 'to theaccompanying drawings,and to the characters o f-reference markedthereon, which forms. :part of this specification.

My invention relates to automobile ;radiators,.and it has for its objectto provide a radiator wherein the parts may berasily made and assembled.It also has gforits object to so connect the parts of 5 the radiatorthat-they may be easily removed when .repair thereof is necessary.

The radiatorsinvolving my invention are formed'- of a plurality ofstrips which are formed shallow trough shaped and which may be placededge to edge,-to produce water cellsor conduits. through which the watermay be carried while it-isbeing cooled by-the air that passes betweenthe cells.- The strips instead of being placed edge to edge may befolded centrally and opposite edges brought into juiztaposition. .Theymaythen be sealedalong the edges which are thus brought together. By myinvention also is provided a spacing-nieanswhich is'formed .in thestrips so that the cells maybe placed inparallelrelation bysmerelybringing the cells together. This will permit .rea'dy assemblage of theparts and form passageways which will permit the. air. to freelypass-between the cells. By my: invention is alsoprov-ided a means,forspacing the edges of the-cells and ,a means which produces localwhirls 'ofthe air as-it passesbotwoen the --cells and also formsaradiating sur- 45Ffaoegto dissipate the heat containedin the waterwhich passes through the cells. The vconstruction.also is-such that ifoneof the cells needs-repair all that is necessary is to -meltsth'esolder along the-points of contact 60. or gconnection with thesothervparts of the :iroEdiator-Wflier'ebyjthe cells-may be removedeandiithewmpairs may be made n the. cell as smayibe ;d ed.;necessary.The--v cell may .zrfthembe.-i'oplaced and :-'re=l$0 .161 .i .pos tion65' inlzhe-radiator. atls inventiona rato a minimum.

trates a number of cells secured together.

diator is produced wherein the water cells are sealed and securedtogether :by a very little solder, thereby greatly reducing the cost ofproduction. In the radiators now known in the art, the overlapping partstake up the solder in great quantities by reason of the capillary actionof, the closely positioned strips, and consequently an enor mousquantity of solder is used. In the preferred form of the constructioninvolvmg my invention there are only-twonarrow edges which are placedside by side and WhlCh are dipped for purposesof-sealing the cells sothat the amountof solder isreduced The invention maybecontained-.inniany forms of heaters, coolersand iheat radiating devicesusable 'for different ,purposes all of which come within .the purview,of my claims hereinafter appended. "ToshoW the practicability of myinvention, I have selected one of such constructions as an example andshall describe it hereinafter. The construction selected is illustratedin the accompanying drawings.

In the drawings, Figure-1 illustrates a front view of the radiator..Fig. 2 illustrates a section of the upper compartment or chamber oftheradiator. Fig. 3 illus- Fig. 4 is an end sectional View ofithecluster shown in Fig. 3. 1Figp15 illustrates a spacing stripwhich islocat'edi'between si e. edges of adjoining cells. IF ig.:5; illustrates.anend sectional view of. the shallow trough shaped and thence itpasses-to. the jackets fofi-the engine. the circulation" being causedbygthe difference in the weight of the water ini the .two parts of-thccircuitby reason-ofi'the difference in the temperature, it-beingheateglby theengineand cooled bythe radiator ingthe manner wella knowninthenrt. I g'Ihe usua1 cap 5; isralso; provided for; closing the funnel ormouth piece 6 through which water or other suitable cooling medium mayoverlap. The overlapping flanges of be poured into the radiator.

The water cells 4 are made of strips 10 sufficiently long to extend fromthe upper compartment. 2 to the lower compartment 3. They are madeshallow trough shaped and formed with flanges 11 and 12 along their sideedges and flanges 13 along their end edges. The strips 10 may be placedside by side in the-manner shown in Fig. 6 and so that the flanges 11,12 are placed in close contact with each. other to form the cells 4:, orthe strips 10 may be bent centrally as shown in Fig. 4 so as to bringopposite side flanges 11 and 12 into contact with each other to form thecells 4. Y i The walls of the cells have a spacing means formed therein;Raised portions 15 are formed in the stamping of the strips 10. Theraised portions 15 may be made in any suitable shape, but they arepreferably made frustumalwhereby flat contact surfaces 16 are fon'med oneach raised portion. The contact .Sur firces or raised portionsofadjoining cells are placed in thrust relation to each other. The cellswhen bound together are thusJield in spaced relation.

The edges of the cells formed by the flanges 11 and 12 arealso held inspaced re lation by a spacing means. In the form of the invention shownthe edge spacing means consists of a plurality of transverse piecespreferably made in the forms of tongues 20 extending from a strip 21.The tongues 20 are twisted so that the plane of each tongue extends atright angles to the plane of the strip 21 forming thereby ashort-twisted or screw shaped portion 22 at thepoint' of connectionbetween the tongue portions and the stripf] The strips 21 are placedcentrally with respect to the side edges of the cells and so that thetongues between" the cells extend in parallel planes across theradiator. .They are secured in this position when the radiator is dippedin'the solder to seal the side edges of the cells 4. 'The slight twistedportion of the tongues operates to cause the air to be turned or whirledsomewhat in its passage through the cells thereby bringing the air intocontact with the walls of the cells. The flanges 13 which extend atright angles to the cells at the top thereof adjoining cells are securedtogether by solder. The structure thus formed 1s secured in po sition inthe radiator between the two chamused for many varied edges of thecells,

' tongues fitting tical cells, the cells havin portions having a len thecells as the water, which passes down through the cells and to theengine, cools 1t.

The construction selected and described may be greatly varied in thearrangement and manufacture of its parts and in the substitution ofelements having equivalent functions and such modifications may bepurposes and still contain the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

1. A radiator having a plurality of vertical cells, the cells havingflanges composed of edges of the sheet metal of the cells sealedtogether, and displaced from the planes of the side Walls of the cells,strips extending centrally with respect to the the strips having tongueslocated in parallel planes extending at r1ght angles to the strips, thetongues fitting the flanges of the cells, and the flanges and tonguessecured together by solder.
